</div>Investigation Overview¶
Over price,confort and security many reason motivate people to choose a specific airlines for their trip. The competition and the mean of taking a plane which is supposed to be on time is extremely important. In fact airlines can't effort to be listed in as most likely to be delayed flight. For those reasons,they have to manage and minimize as much as possible causes of flight delays or flight cancelled.
My main objective is to share important information with the public so that they can know the conditions of cancellation or delay of a flight.

We are studying flight over 2007 , the dataset contains 7453188 fligts records shared in 31 features from 291 differents departures place to 293 destinations in 2007 !

MQ, AA and OO for American Eagle Airlines Inc, respectively American Airlines Inc. and Skywest Airlines Inc ,have the highest number of cancelled flights in 2007 and these airlines also have the highest number of cancellation codes in the national airspace system (non-extreme weather conditions, airport operations, high traffic volume, air traffic control, etc.). In fact, the main reasons for flight cancellation are either the carrier itself or the weather.
